' This invention relates to improvements in the irrigating artandparticularly with sprinklers used in connection" with portable,

underground and overhead and like irrigat' ing systems for all purposes.I

In a sprinkler used in these types of irrigating systems, it isessential that as' l arge' a radius of distribution of" th'e'wate'r aspossible be had from the stand pipe, and also it is imperative thatthere be an even distribution of the water for the entire radius coveredin order tom'ost econom'icallv and efiiciently carryout the irrigatingprocesses. To th s end it has ordinarily been the practice to provide asprinkler with one or more outlet nozzles arranged to prodiice' as greata throw as possible and tocover the complete circle of movement, meansbeingprovided to slowlv rotate tlie'sprinkler; the slower the rotationthe more efficiently the water is distributed Heret'ofore, howev r, thismechanism hasbeeii moreior' less complicated and costly to operate andmaintain;

It is the object of the presentinvention therefore to produce a'sprinkler which is simple, cheap andjdurable andwhicltwilh cover asgreat or greatei' an area than-any" of the costly and complicatedsprinklers now commonly in use; and one which wili reduce thecost ofoverhead installation to a minimum and yet give better results" than theother sprinklers noted.

These objects I accomplish by means or such structure and relatlve'arrangement of characters of reference on the drawings, the

numeral 1 designates the base coupling ar ranged for connection with thestand'pipe and provided with a. swivel cup 2 in its upper end. Thenumeral 3 designates the swivel or rotating pipe of the sprinkler headwhich projects into the swivel cup 2 and is provided at its lower endwith an annular flange 4; to seat against the bottom of the cup 2. Aswivel plug 5 screws into the cup 2, and there is a washer 6 of leatheror the like interposed between the flange 4. and the plug 5 so that'whenthe sprinkler head is under the pressure of the water pass, ingtherethrough there" is no metal to metal bearings, and a perfectlytightjoint is as sur'ed 'to prevent the ingress of dirt or the like and theegress of water.

The swivel plug 5 is-in the form of a short cylindricalbody which fitsclosely around the pipe 3 for the full length ofs'aid p'ipe so as'toform an extending bearing for the pipe and thusprevent it from cant'ingor bind ing with" the rotation of the sprinkler head.

At the upper end of the pipe isthe coupling head 7 connected with whichisfltlie primary outlet nozzle pipe 8 connected into the coupling 7 indirect central aliiienient with the vertical axistliereof'. bent at asubstantial angle of 30'sdegrees. from the vertical, and provided withthe discharge nozzle '9 at its outer endi The numeral 10 designates the.secondary dischange nozzle pipe which connects new the head 7 atsubstantially right angles thereto; and is provided at its? outer end"with a'discharge nozzle 11 mounted adjacent wh'ich'iis a bracket 12'having a projecting arm'1 3, on the outer end of which is a bearingsleeve 14.

A small shaft 15 projects through'the bear ing sleeve 14'. and on oneend thereof is mounted asmall propeller 16 similar to anaeroplane'propeller in shap'e;and on the op posite end of the shaft 15is a; siriallovershot water wheel 1'? mounted in the'path ofthe water tobe discharged throug'lrtheiioz zle 11'. The blades or'paddles of thewater wheell'l'have quitean abrupt. bevel as at 18; so as to scatter thewa ter discharge'd thereagainst .in' a" well distributed manner andalsoto set up a vibrationrelativeto'the water wheel 17 and the propeller16 so as to thoroughly distribute it inside of the circle around thestand pipe. With the parts p0- sit-ioned as shown in Fig. Qthere will bea reactive efi'ectexerted by the issuing water on the nozzle 11 tendingto move the arm 10 in a clockwise direction. The impact of the streamagainst the blades 18. however. will to some small extent neutralizethis reactive effect. However, the driving of the propeller through theaction of the wheel 17 will co-operate with the re-active ettcct of theissuing stream to drive the arm 10 and connected parts ina clockwisedirection.

The vibration set up by the impact of the Water against the wheel 17keeps the rotating head from binding in its hearmgs under the pressureofthe water thereagainst and thus acilitates the rotating action, Thespeed of rotationis controlled by the angle at which the secondarynozzle is placed. The farther itis placed. to the left the greater willbe the speed of rotation of the sprinkler headin a clock-wise,manner andvice versa as it is turned tothe right the speed will be slowed down. it i It will. be seen from the description at the foregoing sprinklerthat hile it very simple and inexpensive to manutacture.

inainta-in andoperate. nevertheless it is capable of performing the fullfunctions for which a sprinkler ofthis type isdcsignml. namely, to throwthe water to the greatest possible radius and to thoroughly discharge itover theentire area to be irrigated, doing all that the moreexpensive,complicated sprinklers now on the market can he pected to do.

readilyseen .thatI have produced such a de vice as substantiallyfulfillsthe objects of i the invention as set forth herein.

cure byLetters Patent is;

While thisspecification sets forth in detail the present and preferredconstructitm of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit of:the invention, as defined. by the appended claims. .Havmg thusClQSCIIlJEd my invention what 1 claim as new and useful and closure tosel. A sprinkler comprising a rotatable head, discharge nozzles.arranged on the head, a propeller supported by the head, the propellerhaving a horizontal axls set at a tangent to an imaginary circle hav ngas its center a point in the vertical axis of the a secondary dischargenozzleat its outer end.

From the foregoingdescription it will he head, and means to impartrotation to the propeller whereby the action of the same against the airwill tend to rotate the head.
